Remarks
See the sample linked on this page for a complete sample showing how to configure this delegate.
It is worth pointing out that the buffers delivered to the DidOutputSampleBuffer method come from a small pool of buffers in AVFoundation, and failure to call Dispose() on the buffers you receive will block the delivery of further frames.
